I have a Wifi network to which I connect at work. The IP address has always been DHCP, but today the DHCP server is down. If I can figure out what IP address I had, I can set it statically (after checking to make sure another device hasn't already taken it, via ping from my desktop).
Does Android have a log anywhere of the IP addresses it is leased? I have root and thus can look at any file on my phone.
